Creation of Plasma Using Audio – Ultrasonic Power for Charged Particle Acceleration

Abstract

The aim objective of this thesis is the study and design of a suitable plasma medium used for particle acceleration. The study reveals that the present plasma can performs plasma wakefields of high gradient in the range of MeV and this wakefield increases with the increase of the discharge pressure. In addition, the choice of that audio frequency at this particular high pressure (≈ 0.2 Torr.) performs highly adapted conditions for the production of high gradient wakefield.

The detected output plasma particles predicts the acceleration of injected ions reaching an energy range exceeding 1 MeV without applying an extracting voltage. Experimental data using computer simulation SRIM expect an energy gain from 4 to 18 MeV.

The present study of a single plasma cell points to the possibility of constructing a long accelerating tube composed from multi-cells to act like drift tubes in the linear accelerator.

Our study is concentrated in the characteristics and diagnosis of one cell (L=27 cm, = 4cm).

The thesis is composed of five chapters in addition to this summary and conclusion.
